I think wifi access for multiple Wiis on the same IP is also blocked by N. So even having 4 consoles, each would need its own separate IP address. Or you'd have to have a built-in LAN feature on the console itself, which is not something that currently exists.

I don't think they do. I've ran Wii's before simultaneously on MarioKart. We all got disconnected once but that was it...
